Abstract
The increase of machine-to-machine (M2M) communications
over cellular networks imposes new requirements
and challenges that current networks have to handle with. Many
M2M UEs (User Equipment) may send small infrequent data,
which suppose a challenge for cellular networks not optimized
for such traffic, where signaling load could increase significantly
and cause congestion over the network. This paper evaluates
current proposals to manage small transmissions over the Long
Term Evolution (LTE) cellular network. We also propose a new
Random Access-based Small IP packet Transmission (RASIPT)
procedure for M2M UEs small data transmissions. Its main
feature is data transfer without establishment of Radio Resource
Control (RRC) connection to reduce signaling overhead. In
our design, we assume a Software Defined Networking-based
architecture for 5G system. When compared with current LTE
scheme, our procedure reduces significantly the signaling load
generated by M2M UEs small transmissions.This work is partially supported by the Spanish Ministry
